CURTAIN-FIXTU RE.

SPECIFICATION forming part of Letters Patent No. 435,018, dated August26, 1890.

Application filed May l1, 1889. Serial No. 310,466. (No model.)

To all whom, it may concern,.- Y

Be it known that I, IIORATIO D. KNIGHT, a citizen of the United States,residing in Lancaster, in the county of Lancaster and State ofPennsylvania, have invented certain I1nprovements in Curtain-Fixtures,of which the following is a specication.

This invention relates to improvements in that class ofcurtain-'fixtures wherein a sp rin groller is used andin which thecurtain can be adjusted higher or lower on the window by means of cords,and can also be rolled or unrolled at whatever position it is placed, soas to shade any part of the window.

The object of the invention is to simplify the construction of fixturesof this class by doing away with the use of guide-rods or any specialattachment whereby the spring` of the roller is prevented from turningthe hanger `to which the supporting-cords are attached,

thereby avoiding the cost of such guide-rods or other specialattaclunent, the strain produced by the frictionbetween the sliding andstationary parts ot' the same, and the locking of those parts while thecurtain is being raised or lowered, caused by the unavoidableirregularity of the two ends of the curtainroller while moving up ordown. `I acco1nplish this object by the mechanism illustrated in theaccompanying drawings, in which- Figure l. is an elevation showing awindow with the curtain-fixture applied. Fig. 2 is a vertical transversesection of the frame on a line between the hanger K and the roller, andshows a side View of the hanger and its connections. Fig. 3 is a similarview of the opposite side of the same with the side ot' the frameremoved. Fig. 4: is an enlarged top View of the right-hand end of theroller with a portion of its fixtures in section on the line @c ce ofFig. 2.

branches, one of which F is carried across the window to and over asimilar sheave G, from which it depends, the lower end being attached toany ordinary hanger H, which supports one end ot the roller. Theotherbranch I of the cord is carried downward and attached to the hangerK, which supports the opposite end of the roller.

peculiar construction of t-he hanger K. As will be seen in Fig. 2,.itconsists of a lobe a, in an opening through which the spindle of theroller is supported, the spindle and the part of the opening in which itrests being of such shape as to prevent the spindle from revolving `inthe opening, and an arm b, projecting backward from the upper end of thelobe and above the spindle d of the roller at an approximate right anglewith the axis ot the roller. This arm is provided with two or moreperforations c, through one of which the cord I is secured. The eiect ofthis construction is such that the leverage of the point at which thecord I is fastened to the arm l; overcomes the tendency of the spring toturn the hanger. This leverage must be regulated by the strength of thespring, for which purpose there are a number ot perforations c throughthe arm b, as before stated. The double cord between the knob m and thesheave E is provided with knots n n at regular intervals to engage theknob fm.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is*

The combination, with a spring-roller and suspension-cord, of a hangerhaving an opening in which the spindle of the roller is immovablysupported, and a projection from the side ol said hanger forming ahorizontal angle with the axis of the spindle, saidiprojection beingadapted to be engaged by the suspension-cord above the spindle atvariable distances horizontally from the said spindle, substantially asspecified.
